Incorrect spelling, explanation: the word stomach seems to have an easy spelling, but still quite a large number of English users spell it wrong by adding the letter -e at the end, which gives a wrong form stomache. The mistake might be the result of the fact that the word is often a part of a collocation stomachache, which ends with an -e letter.
